Nat and Caly thanks for reading. I agree with you both.
@LM I appreciate you responding and reading the blog, I don't think you read this post fully. If you did, maybe you missed some of my points.
When T12 (FL) hit, VP was not available from the T11 instances. They placed a hot fix later to receive VP. http://us.battle.net/wow/en/forum/topic/2795074028?page=4#69
That wasn't really an opinion, it was fact that has been updated and exact quote was:

Removing VP from T11 raids when FL hit.

alluding to the fact that it is NOW there. Sorry if that was perceived wrong in my type.
The next issue you addressed is ilvl, I was NOT saying was the highest ilvl in game. I made a mistake, 378 is from normals and 391 is from heroics. I made a horrible mistake and I'm sorry. Point of that whole paragraph is the guilds that have killed Rags on normal is very low.

Lastly is the nerf to FL being in steps, at the time of the post all the info I had was it would be done:

"by around the same percentage we brought difficulty down for the original Cataclysm raids when Rage of the Firelands (patch 4.2) was released."
